Problem description: I downloaded the Codex App for Windows , and Installed the Codex app and when I launched the Codex App , it Stuck on the Launcher Activity Screen where we see the codex logo and nothing happens, it freezes or gets struck.
OS : Windows 11 (Latest Version)
Solution (that worked for me ) : So if you have been using VS code with codex extension it creates a .codex folder under C:\Users\{Username} if not you may look under %APPDATA% . Create a Backup of .codex folder then delete this folder then Goto Settings >Apps > Installed apps > Codex > then click on Terminate and then click the Reset button once both Terminate and Reset is done then Uninstall the Codex App. Once Uninstall is completed. Restart your system and install the Codex App using the Codex Installer.exe . Once Installation is completed this time you will get the Login screen in the codex app.
Hope this solution works and resolves this issue for you guyz. If this solution works for you guyz please upvote and leave your comments. Thanks.
For me on vscode it sometimes freezes again. Then i just leave the thread and go back in again and it comes up again.. 1/5 times that already works so just keep trying - restart vscode also… and taking a little break helps too.. because you can’t do anything anyways. I think it is an API issue - probably scaling … beside that GPT 5.5 works like a charme.. good work!!!
I found that the issue may be caused by the auth.json file located in the ~/.codex folder.
Solution: Quit the application, delete the auth.json file, and then restart the application. You should be able to log in again.
This solution works on both Windows and Mac. This method also prevents the loss of past conversations and project records
The same. I used gpt 5.5 xhigh in codex cli to solve this problem))) If you want to fix this issue on Windows, please refer to my bug report below:
Title:
VS Code Codex extension webview stuck after auto-update: module import/export mismatch
Environment:
OS: Windows 11
IDE: VS Code
Extension ID: openai.chatgpt
Working rollback version: openai.chatgpt@26.5506.31004
Date observed: 2026-05-14
Screenshot attached: “Step, where Codex crashes.png”
Description:
After VS Code auto-updated the OpenAI/Codex extension, the Codex sidebar stopped rendering the start screen. The extension icon
appears, but the webview does not continue loading into the normal Codex UI.
Expected:
Codex sidebar should render the start screen / chat UI.
Actual:
Only the Codex icon/loading area is visible. The UI never finishes rendering.
Console error observed in the VS Code webview:
SyntaxError: The requested module ‘./external-agent-import-step-C96Jtdue.js’ does not provide an export named ‘t’
Imported by:
./gpu-tearing-debug-settings-Kq9K4yvT.js
Workaround:
Downgrading the extension to openai.chatgpt@26.5506.31004 and pinning it restores the UI.
Notes:
This looks like a packaged webview bundle regression: one generated JS chunk imports an export that the referenced chunk does not
provide.
